Larger than your average Rubik’s Cube, Puzzle Facade is a project by Spanish artist and designer Javier Lloret that transforms this building in Linz, Austria into an interactive puzzle for passers-by to play with:
In Puzzle Facade the player interacts with the specially designed interface-cube. The interface-cube holds electronic components inside that allow for it keep track of its orientation and the rotations of each side of the cube. This data is sent over Bluetooth to a computer that runs the Puzzle Facade designed software. This software changes the lights and color of the large-scale Ars Electronica’s media facade in correlation to the handheld interface-cube.
